CONCRETE-IMIXER OR THE LIKE.

Specification of Letters Patent Patented May 9,1916.

To all whom it may cwwewz;

Be it known that I, OHARLEf-J' W. BRAYTON, it citizen of the United States, residing at Vfeterioo, in the county of Bieekhziwi: and State of Iowa, ha e invented certain new and usefui Imp; :"ili fiilk? in Concrete-Mix ers or the of which the ioiiowing is a description.

My inveniion imionys to that class of devices known inixe and relates part-ioniariy to ihut hype of mixei known as a single hatch mixer pm icuhii'iy adapted for mix ing ('onerete the like. it is particuiarly intended for thai type of mixer which is provided with a ,ilillniitl"ifig one and open and suihihiy rohitabiy supported, that it may be continuously driven to mix the concrete, or riited to disrherge the same, and

relates; niii'ticnlariy to auxiliary supporting ma ns or supporting the drum when. in one of these positions, or if, desired, hot}; in the mixing ir oischarg'ingpositions.

Fig; 1 ;Fig. an and eievation of the mixer shown in: 1, and F L is an. ond'eie'vation of a modified form of the supporting deyiee, arranged to support the drum in eithenxmixing or (.iischarging positions.

Referring to the cirawiiigs, the mixer shown is provided with a frame, or What is coinmoniy allied skids, consisting of the side bars 1 and cross bars 2, which cross bil-IS form a holster when the machine is carried on Wheeis in the Well known manner. Mounted on the frame are a, pair of standards. 4,. 4 of any suitable form, which carry {L yo or iishaped supporting member 5.

The supporting member is preferably pivotaiiy carnied from the standards, so that it may be ranked so as tilt the drum carried thereby. The drum shown comprises a part 6, preferably exteni'ied as at 7, and open attheend, the same iieing mounted upon a shaft 8 carried. the support 5. so that the drum may be rotated on the support. With the type of mixer shown the drmn is provided with a flange 9, having teeiah adapted to mesh with the driving gear or pinion 10, :vhich is extended through the standard and is driven in any desired manner. In Fig. 1, sprockets i1 and 12, and sprocket chain 1.3 are shown fofdriving the pinion 10, 1-1: being ii suitable driving shaft, which may be driven from an internal combustion engine or the like. The rocking of the support 5 may he controlled in. any desired manner, handles 1" being shown for the purpose. T particular rocking 0} ti 'ng iii-2 ism, and locking device iheiefoi. however, is fully de- JQ-Ki in n coiixp nion :ip 'riicsiioii, and need 410i he rieserih i111 herein. It may be nieniionirri, in ii; i..- grasping the Frown to the n Fig. :1, or 9W}? in the hani'iles 1 in the se ne figure.

ohvions 'ihiiidrum supported on a shzift in. the manner described inrows con siiieruhie sir .ii upon the sh i'. mriiouiarly when unite in mixing position and contains a batch of cone-rem. This strain on the shaft 8 may bend. the shzi ft, or cause it to crystallize and break, even though the construction. of shaft and bearing 'weii' designed and suhsmntiaily made. My preferred form of siigifi hearing ieed not he described in fiiii herein, as this forms part of a companion application in which it is fully described and claimed.

The oonstruezion shown for supporting the drum, particuhiriy in its mixing position, is extremely simple, and consists of the two fillers 16, which may be carried from the frame in any desired manner. These roiis are preferably so positioned that they contact with the flange 9, or with the edge of the gear and support a portion of the weighi of the (1mm when the same is thrown to the position indicated by the full lines in Fig. 3. Theare made of any suitwill be carried by the charging the concrete tremely simple, and does not able material, and of any convenient size, and are preferably mounted on or provided with anti-friction rollers or bearings (not shown in detail). In the construction shown, the rolls 16 are rotatably secured on the axles or shafts 17, carried by the brackets 18, securedlto the side frame -1. These brackets are preferably connected and braced by the connecting member 19, and by brace members 20, secured to the standards 4. It will be noted that int'he preferred construction, the brackets 18, or that is, the ends 18 of the same, extend substantially at right angles to the axis of the shaft 8, which carries the drum, so that the shafts 17 carried by the brackets are substantially parallel with the shaft 8, and there is nobinding or excessive friction, When the mixer is thrown to the position for; mixing, while a portion of the thrust is carried by weight and all thelend the shaft 8 and the support 5, a considerable portion .of

rolls 16, and to a'large extent remove the strain from the shaft 8. The rolls also act as a stop for limiting the movement of the drum when thrown tomixing position, preventing its, being thrown far enough to discharge the contents instead of mixing, or straining the handles and look. When the batch .ofconcrete is sufficiently mixed, the drum is thrown to the position indicated by the-dotted lines, disinto wheelbarrows, or wherever desired.

In Fig. 4, additional rolls 16 are shown, positioned on the shafts 17, so that when the drum is thrown to the discharging position, the flange 9 will rest upon the rolls lfi su porting the drum and acting as a stop. this figure therolls 16 are shown the same size as rolls 16, but the of course, may be made larger or smaller, as may be desired. While the rollsv might be carried by the drum, or ,associatedtilting parts, and be arranged to cooperate with construction shown and described is ex- 1n crease the weight of the drum, making it easier to throw or tilt to either position.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without eparting from the spirit of my invention; hence I do notwish to be understood as limiting myself to the exact form, construction, arrangement or combination. of parts herein shown and described, or uses mentioned.
